I have been looking at which coilovers to install with the intent of eventually addind an ARB bumper and winch. From what I have read the SAW's use a 650 lb spring and should be good to go when I add the extra weight, but I may have to crank it up a bit to bring it back to level.

I was looking at the ICON site, an it said something to the effect that it may be a no go with a winch / bumper as it will make the front sag.

Do the ICON / DR co's use a lighter weight spring? What is the spring weight? Will I be good to go with the ICON 2.5?

One a side note, is there any difference in the C/O's that say DR on them and the newer ones which say ICON, or just the leftover stock from Donahoe?
